Magnum Opus. Questions: support@yourgreatestwork.com.

Your journal stays on your computer. Trades, notes, screenshots, check-ins, chats, stats and your strategy are stored only on your computer. Your TopstepX key and sign-in token are kept in your computer’s secure keychain. The app reads your TopstepX account directly from your computer and never places, changes or cancels orders.

What we keep: your email, the name you give, your plan and subscription status, the computers you sign in on (computer name and app version), and a usage record for each AI request (time, feature, model, size and cost). We never keep the content of your messages, charts or the AI’s replies.

When you use the AI, your message, charts and the context the feature needs (such as your strategy, plan and recent trades) pass through our service to Anthropic to generate the reply. Anthropic deletes API data within 30 days, except where it must keep it longer for safety or by law, and doesn’t train on it.

Payments are handled by Stripe. We never see your full card number.

Emails and the waitlist: we send sign-in codes and account emails through Resend. Waitlist and marketing emails go only to people who confirmed, and every one has an unsubscribe link.

Providers: Fly.io (hosting), Anthropic (AI), Stripe (payments), Resend (email), Google Workspace (support email), Vercel and Umami (this website; no cookies). Some are in the United States. We don’t sell your data or use it for advertising.

How long: account data until 30 days after you close your account, usage records 24 months, billing records 5 years (tax law). Your journal stays on your computer until you delete it.

Your rights: you can ask what we hold, get a copy, correct it, delete it or withdraw consent at support@yourgreatestwork.com, and we’ll answer within 15 days. Magnum Opus is for people 18 and over.
